Recently, a new kind of collinear magnetism, dubbed altermagnetism, has attracted considerable interests. A key characteristic of altermagnet is the momentum-dependent band and spin splitting without net magnetization. However, finding altermagnetic

BaNi$_2$As$_2$ is a nonmagnetic analogue of the iron pnictide superconductors, and in its tetragonal state exhibits an incommensurate charge-density-wave (IC-CDW) and a sizable elastoresistance. In this work, phonons in BaNi$_2$As$_2$ associated with
